374 Latest Features
High Performance

High Performance

  • The 374 can load up to 33 trucks per hour with 36 tonne (40 ton) capacity.
  • Swing torque increase of 10 percent makes cycle times faster than the previous series.
  • Multifunctioning is smoother and more efficient with the hydrostatic swing circuit.
  • Enhanced heavy lift mode increases system pressure to help you pick and place heavy material with ease.
  • Booms, sticks, and frames are up to two times more durable than the previous series, which will give you years of reliable performance in the harshest environments.
  • Match the excavator to the job with three operating modes: Power, Smart, and ECO.
  • Advansys™ bucket tips increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.
  • Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
  • Don’t let the temperature stop you from working. This excavator has a high-ambient capability of 52° C (125° F) and standard cold start capability of –18° C (-0.4° F).

Boost Efficiency and Productivity

  • Boost productivity up to 45% versus traditional grading with standard Cat Grade with 2D system – includes indicate-only and laser capability.
  • Standard Grade Assist helps you stay on grade – simply and effortlessly – with single-lever digging.
  • Upgrade easily to optional Cat Grade with Advanced 2D or 3D.
  • Automatically stop excavator swing at operator-defined set points in truck loading and trenching applications with Swing Assist.
  • Standard Cat Payload on-board weighing helps you achieve precise load targets and increase loading efficiency with real-time payload estimates.
  • Standard Product Link provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data on demand through VisionLink online interface, helping you improve jobsite efficiency with lower operating costs.
  • VisionLink™ helps you remotely manage production targets. The monitor's USB port lets you download your results from one shift all the way up to 30 days of work so you can manage progress without needing an internet connection or VisionLink subscription.
  • All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica. Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.
  • Remote troubleshoot connects you to a dealer service pro to help solve your problem and quickly get you to work.
  • Remote flash works around your schedule to ensure your machine's software is up to date for optimal performance.

Boost Efficiency and Productivity with Cat Technology
Work In Comfort in the All-New Cab

Work In Comfort

  • Choose between Deluxe and Premium cabs – both with automatic climate control.
  • Stay warm with the Deluxe heated seat; stay warm and cool with the Premium heated and ventilated seat.
  • Get in and out of the cab easier using the tip-up left console.
  • Advanced viscous mounts reduce cab vibration up to 50 percent over previous excavator models.
  • Control the excavator comfortably with easy-to-reach controls all located in front of you.
  • Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles.
  • Use the standard radio’s USB ports and Bluetooth® technology to connect personal devices and make hands-free calls.

Simple to Operate

  • Start the engine with a push button; use a Bluetooth key fob or the unique Operator ID function.
  • Program each joystick button, including power mode, response, and pattern, using Operator ID; the machine will remember what you set each time you go to work.
  • Program up to four depth and slope offsets so you can easily get to grade without a grade checker – a real time saver and safety enhancer on the jobsite.
  • Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds – all to prevent wear and tear on the attachment and excavator.
  • Automatic hydraulic oil warmup gets you to work faster in cold temperatures and helps prolong the life of components.
  • Navigate quickly on the standard high-resolution 254 mm (10 in) touchscreen monitor or with the aid of the jog dial control.
  • A second 254 mm (10 in) monitor is available for the Cat Grade with Advanced 2D and Cat Grade with 3D.
  • The Cat PL161 Attachment Locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. The excavator’s onboard Bluetooth reader will locate the device automatically.
  • Save more time and energy with available work tool recognition. A simple shake of the attached tool confirms its identity; it also ensures all the attachment settings are correct so you can get to work quickly and efficiently.
  • Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.
  • Make moving the excavator much easier with Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.
  • Need more lift during your shift? Auto heavy lift gives you 8% more power when you need it for as long as you need it.

Simple to Operate
Less Maintenance

Less Maintenance

  • Expect up to 20 percent less maintenance cost than the 374F due to reduced hydraulic oil capacity and extended and synchronized service intervals
  • The excavator is auto lube ready with built-in mounting points; an available auto lube retrofit kit provides additional hardware to mount a grease pump and line guards.
  • Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
  • Using Cat genuine oil and filters and doing typical S∙O∙S monitoring will double the current service interval to 1,000 hours, giving you greater uptime to do more work.
  • The advanced air intake filter with pre-cleaner has double the dust holding capacity of the previous air intake filter.
  • The hydraulic oil filter provides improved filtration performance and longer 3,000 hour replacement interval – 50 percent longer than previous filter designs.
  • The high-efficiency hydraulic fan has an automatic reverse function to keep cores free from debris, eliminating the need for any operator interaction.
  • S∙O∙S ports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.

Enhanced Safety

  • Standard 2D E-Fence is integrated right out of the factory, which prevents the excavator from moving outside of operator-defined set points.
  • Lift Assist helps you avoid tipping by letting you know if your load is within the excavator’s safe working range limits.
  • Rear and right-hand-sideview cameras are standard. Upgrade to 360° visibility and you’ll easily visualize objects and personnel around the excavator in a single view.
  • See all around the machine with the premium 360° lighting package and its 1800 lm lights on the chassis, cab, boom, sides, and rear.
  • Serrated steps and anti-skid punch plate on the service platform help prevent slipping.
  • A travel direction indicator helps operators know which way to activate the travel levers.
  • Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab pillars, larger windows, and a flat engine hood design.
  • A ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
